TECHNICAL FIELD

The present invention relates generally to electronic devices, and moreparticularly to memory devices.

BACKGROUND ART

Security is a critical issue with almost all aspects of computer use.Storage media, such as hard disk drives attached to computers, containvaluable information, which is vulnerable to data theft. A great deal ofmoney and effort is being applied to guarding personal, corporate, andgovernment security information.

As portable memory storage devices have become smaller, easier to lose,more ubiquitous, cheaper, and larger in memory capacity, they have cometo pose extraordinary security problems. It is now possible to downloadmassive amounts of information surreptitiously into portable memorystorage devices, such as universal serial bus flash and micro drives,cellphones, camcorders, digital cameras, iPODs, MP3/4 players, smartphones, palm and laptop computers, gaming equipment, authenticators,tokens (containing memory), etc.—in general, a mass storage device(MSD).

More specifically, there are millions of MSDs being used for backup,transfer, intermediate storage, and primary storage into whichinformation can be easily downloaded from a computer and carried away.The primary purpose of any MSD is to store and retrieve “portablecontent,” which is data and information tied to a particular owner not aparticular computer.

The most common means of providing storage security is to authenticatethe user with a computer-entered password. A password is validatedagainst a MSD stored value. If a match occurs, the drive will open. Or,the password itself is used as the encryption key to encrypt/decryptdata stored to the MSD.

For drives that support on-the-fly encryption, the encryption key isoften stored on the media in an encrypted form. Since the encryption keyis stored on the media, it becomes readily available to those willing tocircumvent the standard interface and read the media directly. Thus, apassword is used as the key to encrypt the encryption key.

For self-authenticating drives, their authentication sub-system isresponsible for maintaining security. There is no dependency on a hostcomputer to which it is connected. Thus, a password cannot (or need not)be sent from the host in order to unlock the MSD. In fact, theencryption key no longer needs to be stored on the media. Theauthentication subsystem becomes the means for managing encryption keys.

Thus, a need still remains for improved security. In view of theever-increasing commercial competitive pressures, along with growingconsumer expectations and the diminishing opportunities for meaningfulproduct differentiation in the marketplace, it is critical that answersbe found for these problems. Additionally, the need to reduce costs,improve efficiencies and performance, and meet competitive pressures,adds an even greater urgency to the critical necessity for findinganswers to these problems.

Solutions to these problems have been long sought but prior developmentshave not taught or suggested any solutions and, thus, solutions to theseproblems have long eluded those skilled in the art.

BEST MODE FOR CARRYING OUT THE INVENTION

The following embodiments are described in sufficient detail to enablethose skilled in the art to make and use the invention. It is to beunderstood that other embodiments would be evident based on the presentdisclosure, and that system, process, or mechanical changes may be madewithout departing from the scope of the present invention.

In the following description, numerous specific details are given toprovide a thorough understanding of the invention. However, it will beapparent that the invention may be practiced without these specificdetails. In order to avoid obscuring the present invention, somewell-known circuits, system configurations, and process steps are notdisclosed in detail.

Likewise, the drawings showing embodiments of the system aresemi-diagrammatic and not to scale and, particularly, some of thedimensions are for the clarity of presentation and are shown exaggeratedin the drawing FIGs. Where multiple embodiments are disclosed anddescribed having some features in common, for clarity and ease ofillustration, description, and comprehension thereof, similar and likefeatures one to another will ordinarily be described with similar or thesame reference numerals. Similarly, although the views in the drawingsfor ease of description generally show similar orientations, thisdepiction in the FIGs. is arbitrary for the most part. Generally, theinvention can be operated in any orientation.

The term “system” as used herein refers to and is defined as the methodand as the apparatus of the present invention in accordance with thecontext in which the term is used. The term “method” as used hereinrefers to and is defined as the operational steps of an apparatus.

For reasons of convenience and not limitation, the term “data” isdefined as information that is capable of being produced by or stored ina computer. The term “data security system” is defined as meaning anyportable memory device incorporating a storage medium. The term “storagemedia” as used herein refers to and is defined as any solid state, NANDFlash, and/or magnetic data recording system. The term “locked” refersto the data security system when the storage media is not accessible andthe term “unlocked” refers to the data security system when the storagemedia is accessible.

There are generally two methods to make a storage device tamperresistant:

-   -   1. Apply epoxy to components—an epoxy resin applied to the        printed circuit board can make it difficult to disassemble the        storage device without destroying storage media.    -   2. Encrypt memory data—data gets encrypted as it is written to        the storage media and an encryption key is required to decipher        the data.

Referring now to FIG. 1, therein is shown a schematic of a data securitysystem 100 in accordance with an embodiment of the present invention.The data security system 100 consists of an external communicationchannel 102, an authentication subsystem 104, and a storage subsystem106.

The storage subsystem 106 is electronic circuitry that includes aninterface controller 108, an encryption engine 110, and a storage media112. The storage media 112 can be an internal or external hard diskdrive, USB flash drive, solid state drive, hybrid drive, memory card,tape cartridge, and optical media including optical disk (e.g., Blu-raydisk, digital versatile disk or DVD, and compact disk or CD). Thestorage media 112 can include a data protection appliance, archivalstorage system, and cloud-based data storage system. The cloud storagesystem may be accessed utilizing a plug-in (or “plugin”) application orextension software installed in a browser application, either on thehost computer or on another system coupled to the host computer via awired or wireless network, such as RF or optical, or over the world wideweb.

The interface controller 108 includes electronic components such as amicro-controller with the encryption engine 110 of software or hardware,although the encryption engine 110 can be in a separate controller inthe storage subsystem 106.

The authentication subsystem 104 is electronic circuitry that includesan authentication controller 114, such as a micro-controller, which mayhave its own non-volatile memory, such as an electrically erasableprogrammable read-only memory (EEPROM).

The external communication channel 102 provides a means of exchangingdata with a host computer system 120. Universal Serial Bus (USB) is oneof the most popular means to connect the data security system 100 to thehost computer system 120. Other examples of the external communicationchannel 102 include Firewire, wireless USB, Serial ATA (SATA), HighDefinition Multimedia Interface (HDMI), Recommended Standard 232(RS-232), and radio frequency wireless networks.

The interface controller 108 is capable of translating USB packet datato data that can be written to the storage media 112 in a USB FlashDrive.

The encryption engine 110 is implemented as part of the interfacecontroller 108 and takes clear text and/or data (information) from thehost computer system 120 and converts it to an encrypted form that iswritten to the MSD or the storage media 112. The encryption engine 110also converts encrypted information from the storage media 112 anddecrypts it to clear information for the host computer system 120. Theencryption engine 110 can also be a two controller subsystem with anencryption controller that has the encryption capability toencrypt/decrypt data on the fly along with managing the communicationprotocol, memory, and other operating conditions and acommunication/security controller for handling the communication,encryption key management, and communications with the encryptioncontroller.

An encryption key 116 is required by the encryption engine 110 toencrypt/decrypt the information. The encryption key 116 is used in analgorithm (e.g., a 256 bit Advanced Encryption Standard (AES)encryption) that respectively encrypts/decrypts the data by anencryption algorithm to render data unreadable or readable. Theencryption key 116 can be stored either internally or externally to theauthentication controller 114.

The encryption key 116 is transmitted to the encryption engine 110 bythe authentication subsystem 104 once a user 122, having anidentification number or key, has been verified against anauthentication key 118.

It has been discovered that, by the employment of the authentication key118 and the encryption key 116, portable memory storage devices of thevarious embodiments of the present invention can be provide an extremelyhigh level of security previously not available in such devices.

When the data security system 100 is locked, the authentication key 118remains inside the authentication subsystem 104 and cannot be read fromoutside. One method of hiding the authentication key 118 is to store itin the authentication controller 114 in the authentication subsystem104. Setting the security fuse of the authentication controller 114makes it impossible to access the authentication key 118 unless theauthentication controller 114 allows retrieval once the user 122 hasbeen verified. Many micro-controllers come equipped with a security fusethat prevents accessing any internal memory when blown. This is awell-known and widely used security feature. Such a micro-controllercould be used for the authentication controller 114. The authenticationcontroller 114 can be a micro-controller or microprocessor.

The authentication key 118 can be used as in several capacities:

-   -   1. As the encryption key 116 to encrypt/decrypt the information        directly.    -   2. As a key to recover the encryption key 116 stored in the data        security system 100 that can be accessed by the interface        controller 108.    -   3. Used for direct comparison by the interface controller 108 to        activate the external communication channel 102.

Referring now to FIG. 2, therein is shown an illustration of anauthentication key delivery method used with the data security system100. In this illustration, the authentication key 118 and the encryptionkey 116 are one and the same. The encryption engine 110 employs theauthentication key 118 as the encryption key 116.

The user 122 must interact with the authentication subsystem 104 byproviding user identification 202, a number or key, to theauthentication subsystem 104. The authentication subsystem 104 validatesthe user 122 against the authentication key 118. The authenticationsubsystem 104 then transmits the authentication key 118 as theencryption key 116 to the interface controller 108.

The encryption engine 110 in the interface controller 108 employs theauthentication key 118 to convert clear information to encryptedinformation and encrypted information to clear information along achannel 206. Any attempt to read encrypted information from the storagemedia 112 without the encryption key 116 will generally result ininformation that is unusable by any computer.

Referring now to FIG. 3, therein is shown an illustration of differentsystems for the user 122 to interact with a data security system 300.The interaction can be by a communication combination 301, which can beby a physical contact, wired connection, or wireless connection from acell phone, smartphone, smart watch, wearable appliance, or otherwireless device.

In one authentication system, a mobile transceiver 302 is employed totransmit user identification 304 to a data security transceiver 306 inan authentication subsystem 310. For exemplary purposes, transceiversare employed for bi-directional communication flexibility but atransmitter-receiver combination for uni-directional communication couldalso be used. The authentication subsystem 310 includes theauthentication controller 114, which is connected to the interfacecontroller 108 in the storage subsystem 106. The user identification 304is supplied to the data security transceiver 306 within theauthentication subsystem 310 by the mobile transceiver 302 from outsidethe storage subsystem 106 of the data security system 300. The wirelesscommunication may include Wireless Fidelity (WiFi), Bluetooth (BT),Bluetooth Smart, Near Field Communication (NFC), Global PositioningSystem (GPS), optical, cellular communication (for example, Long-TermEvolution (LTE), Long-Term Evolution Advanced (LTE-A)), Code DivisionMultiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA),Universal Mobile Telecommunications System (UMTS), Wireless Broadband(WiBro), or Global System for Mobile Communications (GSM), and thelike).

The authentication subsystem 310 validates the user 122 against theauthentication key 118 by a code sent from the mobile transceiver 302being validated against the authentication key 118. The authenticationsubsystem 310 then transmits the encryption key 116 to the interfacecontroller 108 across the communication combination 301.

The encryption engine 110 then employs the encryption key 116 to convertclear information to encrypted information and encrypted information toclear information along the channel 206. Any attempt to read encryptedinformation from the storage media 112 without the encryption key 116will result in information that is unusable by the host computer system120.

In an optional second authentication mechanism, the authenticationsubsystem 310 validates the user 122 against the authentication key 118by having the user 122 employ a biometric sensor 320 to supply abiometric input 322 to verify his/her identity as an authorized user.Types of biometric identification include a fingerprint, an iris scan, avoice imprint, etc.

In an optional third authentication mechanism, The authenticationsubsystem 310 validates the user 122 against the authentication key 118by having the user 122 employ an electro-mechanical input mechanism 330to supply a unique code 332 to verify his/her identity as an authorizeduser. The unique code 332 can include a numerical, alphanumeric, oralphabetic code, such as a PIN. The electro-mechanical input mechanism330 is within the authentication subsystem 310. The electro-mechanicalinput mechanism 330 receives the unique code 332 from the user 122 fromoutside of the data security system 300. The unique code 332 is suppliedto the electro-mechanical input mechanism 330 within the authenticationsubsystem 310 from outside the storage subsystem 106 of the datasecurity system 300.

No matter which method is used to validate the user 122, theauthentication key 118 and the encryption key 116 remain hidden untilthe user 122 is authenticated.

Referring now to FIG. 4, therein shows an illustration of how the user122 can employ the host computer system 120 to interact with a datasecurity system 400.

The host computer system 120 is provided with a host application 402.The host application 402 is software or firmware, which communicatesover the external communication channel 102 of the data security system400.

The host application 402 delivers host identifiers 406, such as internalcomponent serial numbers (e.g. hard drive), media access control (MAC)address of a network card, login name of the user, network InternetProtocol (IP) address, an ID created by the data security system andsaved to the host, an ID created by the data security system and savedto the network, etc., associated with its environment. The hostidentifiers 406 are employed by an authentication subsystem 408 in thedata security system 400.

When the authentication subsystem 408 validates the user 122 against theauthentication key 118 by verifying the host identifiers 406, the datasecurity system 400 will unlock.

For example, the user 122 connects the data security system 400 that islocked to the host computer system 120. The host application 402 sendsthe MAC address of its network card to the data security system 400. Thedata security system 400 recognizes this MAC address as legitimate andunlocks without the user 122 of FIG. 1 having to enter useridentification. This is implementation does not require any interactionwith the user 122. In this case, it is the host computer system 120 andits associated environment that are being validated.

The data security system 400 includes: providing the authentication key118 stored in the authentication subsystem 104; providing verificationof the host computer system 120 by the authentication subsystem 104;presenting the encryption key 116 to the storage subsystem 106 by theauthentication subsystem 104; and providing access to the storage media112 by the storage subsystem 106 by way of decrypting the storage mediacontent.

The data security system further includes the authentication subsystem104 for interpretation of biometric input and verification of the user122.

The data security system further includes using the authentication key118 as the encryption key 116 directly.

The data security system further includes using the authentication key118 to decrypt and retrieve the encryption key 116 used to decipherinternal content.

The data security system further includes the authentication subsystem104 for interpretation of signal inputs and verification of sendingunit.

The data security system further includes the authentication subsystem104 for interpretation of manually entered input and verification of theuser 122.

The data security system further includes the authentication subsystem104 for interpretation of input sent by a host resident softwareapplication for verification of the host computer system 120.

The data security system as further includes the encryption engine 110outside the interface controller 108 but connected to the externalcommunication channel 102 for the purpose of converting clear data toencrypted data for unlocking the data security system 100.

Referring now to FIG. 5, therein is shown a data security method 500employing user verification for the data security system 100. The datasecurity method 500 includes; verifying the user against anauthentication key in a block 502; employing the authentication key forretrieving an encryption key in a block 504; and employing theencryption key for allowing unencrypted communication through a storagesubsystem between a host computer system and a storage media in a block506.

Referring now to FIG. 6, therein is shown an exemplary data securitycommunication system 600. The exemplary data security communicationsystem 600 includes a mobile device 610, a data security system 620, ahost computer 630, and a server/console 640. The mobile device 610 andthe server/console 640 are connected by wired or wireless connectionsthrough a cloud 650, which can be an Internet cloud. The mobile device610 and the data security system 620 are connected by the communicationcombination 301.

The communication combination 301 in the exemplary data securitycommunication system 600 includes a mobile transceiver 612 in the mobiledevice 610 with an antenna 614 wirelessly communicating with an antenna622 of a data security transceiver 624 in the data security system 620.

The mobile device 610 in one embodiment can be a smartphone. In themobile device 610, the mobile transceiver 612 can be connected toconventional mobile device components and to a data security systemapplication 618, which provides information to be used with the datasecurity system 620.

The data security transceiver 624 is connected to a security controller626, which can contain identification, passwords, profiles, orinformation including that of different mobile devices that can accessthe data security system 620. The security controller 626 is connectedto subsystems similar to the authentication subsystem 310, the storagesubsystem 106 (which in some embodiments can have encryption to encryptdata), and the external communication channel 102.

The external communication channel 102 is connectable to the hostcomputer 630 to allow, under specified circumstances, access to data inthe storage subsystem 106.

One implementation of the data security system 620 can eliminate thebiometric sensor 320 and the electro-mechanical input mechanism 330 ofFIG. 3 with only a wireless link to the mobile device 610, such as asmartphone. It has been found that this implementation makes the datasecurity system 620 more secure and useful.

The data security system application 618 allows the mobile device 610 todiscover all data security systems in the vicinity of the mobile device610 and show their status (locked/unlocked/blank, paired/unpaired etc.).

The data security system application 618 allows the mobile device 610 toconnect/pair, lock, unlock, change the name and password, and reset alldata on the data security system 620.

The data security system application 618 allows the mobile device 610 toset an inactivity auto-lock so the data security system 620 willautomatically lock after a predetermined period of inactivity or to seta proximity auto-lock so the data security system 620 will be lockedwhen the mobile device 610 is not within a predetermined proximity for apredetermined time period (to improve reliability and avoid signalde-bouncing).

The data security system application 618 allows the mobile device 610 toremember a password, use TouchID, and Apple Watch (both TouchID andApple Watch mentioned here as examples only, there are many other mobiledevices with biometric sensors and wearables that can be used in asimilar mode) so data security system 620 could be unlocked withoutentering re-entering a password on the mobile device

The data security system application 618 allows the mobile device 610 tobe set to operate only with a specific mobile device, such as the mobiledevice 610, so the data security system 620 cannot be unlocked withother mobile devices (1Phone).

The data security system application 618 allows the mobile device 610 toset the data security system 620 to Read-Only

The data security system application 618 allows the mobile device 610 tooperated in User Mode or Administrator Mode (administrator's modeoverrides user's settings) and use the server/console 640. Theserver/console 640 is a combination of a computer with a console forentering information into the computer.

The server/console 640 contains a user management database 642, whichcontains additional information that can be transmitted over the cloud650 to the mobile device 610 to provide additional functionality to themobile device 610.

The user management database 642 allows the server/console 640 to createand identify users using UserID (username and password) and block/allowunlocking the data security system 620 and provide remote help.

The user management database 642 allows the server/console 640 toremotely reset or unlock the data security system 620.

The user management database 642 allows the server/console 640 toremotely change the data security system user's PIN.

The user management database 642 allows the server/console 640 torestrict/allow unlocking data security system 620 from specificlocations (by using geo-fencing)

The user management database 642 allows the server/console 640 torestrict/allow unlocking data security system 620 in specified timeperiods and different time zones

The user management database 642 allows the server/console 640 torestrict unlocking data security system 620 outside of specifiedteam/organization/network etc.

Referring now to FIG. 7, therein is shown an administrator sequencingdiagram showing the sequence of operations between the mobile device 610and the data security system 620.

Connectivity 700, between the data security system 620 and the mobiledevice 610, is first established with mutual discovery of the otherdevice or system, pairing the device and system, and connection of thedevice and system. The connectivity 700 is secured using a sharedsecret, which is then used to secure (encrypt) communications betweenthe data security system 620 and the mobile device 610 for all futurecommunication sessions. A standard encryption algorithm is selected tobe both efficient to run on the data security system 620 and to beapproved by world-wide security standards.

The connectivity 700 is maintained by the data security systemapplication 618 or the security controller 628 or both operatingtogether as long as the data security system 620 and the mobile device610 are within a predetermined distance of each other. Further, if thepredetermined distance is exceeded, the connectivity 700 is maintainedfor a predetermined period of time after which the data security system620 is locked.

After connection of the mobile device 610 and the data security system620, a data security system administrator application start operation702 occurs in the mobile device 610. Then an administrator sets apassword in an administrator password operation 704. Also afterconnection of the mobile device 610 and the data security system 620,the data security system 620 is connected to the host computer 630 ofFIG. 6 to be powered up and discoverable by the host computer 630 in adata security system connected, powered and discoverable operation 706.

After the administrator password operation 704, the mobile device 610sends a set administrator password and unlock signal 708 to the datasecurity system 620. The set administrator password and unlock signal708 causes an administrator password set and data security systemunlocked operation 716 to occur in the data security system 620.

When the administrator password set and data security system unlockedoperation 716 is completed, a confirmation: data security systemunlocked signal 712 is sent to the mobile device 610 where aconfirmation: data security system unlocked as administrator operation714 operates. The confirmation: data security system unlocked asadministrator operation 714 permits a set other restrictions operation716 to be performed using the mobile device 610. The set otherrestrictions operation 716 causes a set administrator restrictionssignal 718 to be sent to the data security system 620 where theadministrator restrictions are set and a confirmation: restrictions setsignal 720 is returned to the mobile device 610. Thereafter, the mobiledevice 610 and the data security system 620 are in full operativecommunication.

Because it is possible to communicate with the data security system 620without having physical contact with the data security system 620, it isrequired that significant interactions with the data security system 620be accompanied by a data security system unique identifier that iseither printed on the data security system 620 itself, or that comeswith the data security system 620 packaging and is readily available tothe data security system 620 owner.

On making requests that could affect user data, such as unlocking orresetting the data security system 620, this unique identifier (uniqueID) is required. Attempts to perform these operations without thecorrect identifier are ignored and made harmless. The unique identifieris used to identify the data security system 620 to the mobile device610 in a way that requires the user to have physical control over thedata security system 620 and to verify the connectivity 700 isestablished between the authorized, previously paired device and system,such as the mobile device 610 and the data security system 620. Once thedevices are paired, the shared secret is used to make the communicationconfidential.

Pairing connotes that a mobile device and a data security system have aunique and defined relationship established at some time in the past andenduring.

The unique identifier makes for giving the user some control over thedata security system when the user has physical control of the datasecurity system.

To increase the security of the communication with the data securitysystem 620 where the mobile device 610 is a smartphone, a user maychoose to enable a feature, such as a feature called 1Phone here. Thisfeature restricts significant user interactions with the data securitysystem 620 to one and only one mobile device 610. This is done byreplacing the data security system unique identifier described abovewith a random identifier shared securely between the data securitysystem 620 and the mobile device 610. So, instead of presenting the datasecurity system unique identifier when, for example, the user unlocksthe data security system 620, the 1Phone identifier must be giveninstead. In effect, this makes the user's mobile device 610 a secondauthentication factor for using the data security system 620 in additionto a PIN or password. As an example, the paired user phone selected as“1Phone” can be used without a PIN, and as the user-authenticationsingle factor and/or in a combination with any other user-authenticationfactors. If such feature (1Phone) is selected, the data security system620 cannot be open with any other phones, except if an administrator'sunlock was enabled before.

It will be understood that other embodiments can be made to require anadministrat'r's password on the data security system 620 in order to usethe 1Phone feature. Another embodiment may require that theserver/console 640 is capable of recovering the data security system 620in case the 1Phone data is lost on the mobile device 610.

The user may enable a proximity auto-lock feature for the data securitysystem 620. During a communication session, the data securitytransceiver 624 of FIG. 6 reports to the data security system 620 asignal strength measurement for the mobile device 610. The data securitysystem application 618 on the mobile device 610 sends the data securitysystem 620 both the originating signal power level and the threshold forproximity.

Because the signal strength varies due to environmental conditionsaround the transceivers, the data security system 620 mathematicallysmoothes the signal strength measurements to reduce the likelihood of afalse positive. When the data security system 620 detects that thesignal power received has dropped below a defined threshold for apredetermined period of time, it will immediately lock the data securitysystem 620 and prevent access to the storage subsystem 106 of FIG. 6.

The data security system 620 could be used in three different modes: aUser Mode where the functionalities of the data security system 620 aredetermined by the user; an Administrator Mode where an administrator canset an Administrator password and enforce some restrictions on the datasecurity system 620 (e.g., automatic lock after a predetermined periodof inactivity, Read-Only, 1Phone) and where restrictions cannot beremoved by a User; and a Server Mode where an administrator role is setwhere the server/console 640 can remotely reset the data security system620, change user passwords, or just unlock the data security system 620.
